Boot pool status is ONLINE: One or more devices has experienced an unrecoverable error

[goalstopper]

Good Afternoon,

Any help is appreciated..
Running - TrueNAS-12.0-U6
I had a power outage a couple weeks ago. After powering the NAS back on I noticed an alert.

CRITICAL
Boot pool status is ONLINE: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected..

The Boot Pool is the USB thumb drive I have running the NAS software, its 14gb. When i attempt to run a SMART test on it, fails with -

Read Device Identity failed: scsi error unsupported scsi opcode A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

Ran the following command - results below
root@truenas[~]# zpool status -x
pool: boot-pool
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.

using 'zpool clear' or replace the device with 'zpool replace'.

The NAS appears stable and working as expected, I'm just wondering if i should be proactive in attempting to fix any potential future problems?

Download your configuration file and save it somewhere secure.

Your USB thumb drive is at risk of wearing out; these little buggers do not have wear leveling or much endurance. It is best to replace it with a small SSD if possible.

Once you've replaced the boot device, reinstall TrueNAS and upload your configuration file. This will eliminate any hidden corruptions or issues.

1) Download your config file from the NAS to a PC or laptop

2) Burn a new ISO of TrueNAS of the same or newer version (or Rufus a thumb drive or do an IPMI ISO boot or whatever)

3) Power down. Replace your faulty device.

4) Boot into the ISO image and install TrueNAS.

5) Boot the newly installed appliance.

6) Go to the URL displayed on the VGA console and then upload the config file.

7) Have a beer.
